Frequently Asked Questions
Who should use KL-400SFG and why?
Lighting technicians, electricians, and power distribution professionals working with 400A temporary power systems will benefit from KL-400SFG. Its green housing provides instant visual phase identification, while the Santoprene TPV (Thermoplastic Vulcanizate) housing rated to 105 degrees Celsius ensures durability in demanding field conditions.
What voltage and amperage is KL-400SFG rated for?
KL-400SFG carries a maximum rating of 400A and 600V AC / 250V DC. It accepts wire gauges from #6 to 4/0 AWG (UL evaluated with 4/0 AWG), making it suitable for the conductor sizes typically used in 400-amp power distribution circuits.
Why choose the green version of the K-LOK 400A female panel mount receptacle?
Green identifies the equipment ground conductor in North America. Under IEC conventions, protective earth is green-yellow. Ground integrity is critical for personnel safety, and a distinct green connector ensures the safety earth is never confused with a current-carrying phase. Choosing KL-400SFG in green ensures your power distribution system follows established color conventions, speeding up setup and reducing wiring errors.
Is KL-400SFG UL listed and what does that mean?
Yes. KL-400SFG is UL Listed under UL File Number E332947, meaning UL has independently tested and certified it to UL 1691 for the United States. The listing covers the United States.
What industries commonly use KL-400SFG?
KL-400SFG is used across live events and touring, film and broadcast, rental and staging inventories, and industrial temporary power. Its 400A / 600V AC / 250V DC rating, combined with CAM-type universal compatibility and green phase coding, makes it a versatile choice across the entertainment, construction, and industrial sectors.
